To all whom it may concern:

Be itv known that I, WALLACE G. SAND- ronD, a citizen ofthe United States, residing at Davenport, in the ooun'tyof Scott and State of Iowa, have invented new and useful Improvementein Portable Vulcanizers, of which the following isv a full, clear, and exact description.

My invention relates to vulcaniaers, and particularly portable vulcanizer, for repairiogineted .tires `for vleh'ellee, Suoh ae illus-Y treied and .deeerihed the pending erelication of James Scotuensonftiled in the United States Patent 4Qi'li'ce, Noyember lith, 1913, `Serial' No. 733,384. Experience v has Shown .thatthe 4flames generated in the cornbugtion compartment of the said yulcanizer flicker and act in a .very erratic A than-naar' when the burning eeeee thrown oli hv the heated combustible fluid have to dependupon the air et the too oftheeomeertmelit for the necessary oxygen ,to produce Combustion, and also show that these flickering llames Vare elet. te. Ydrift toward .and against the tire ehove the villoenizer., particularly when air ie combined yitheeiol burning geeee at ,a Suitable point in the eomhustori'oompertment below the topof the vulcanizer.

The obiecte of my improvements are to Promote the `eeuhhUetion .of `the geeolehe or othein combustible Huid in the combustion compartment below the top of `the same so as to more 1effectively' and quickly heat the Water in the adjoining compartment, andto provide means for preventing the heroes from ,Comines in eohieet with the tire- This i accomplish by 4the ineens hereinafter folly described and as particularly pointed ,out in theleime In tlr drawings: Figure Y1 is a eide vievv of my imorore viiieehizer Fig- 2 .e verieal Isection therethrough.

A The "Water compartment is, preferably, divided into Va Series of vertical cells by eoluiedietant division-Walle, 0, c, .that connect the vulcanizingplate and partition and have their lower edges terminate-` above the bottom of .the compartment `so that said cells ,may communicate with lone another. i

The eubical ydimen sions of the combustion compartment are, preferably, larger than thosel of the Water compartment, and it is also `diyided into a Series of chambere or lues by .equifdistant parallel Vdivision Walls d, ,that connect partition C and the outer Well @bei the fiileehizer and that, prefer* ably, aline'ivith division-Walls .0, c, or not, according as desired.

ably, removably attached to said tegral members of the vulcanizer to a greater extent than would be possible if the flames were generated higher up'.

The/flames orproducts of combustion issuing from the 'top of the combustion chamber are liable to be blown by the air currents against the tire above the water'- chamber, and injure the same, and this tendency is increased by the presence of slot E. I have, therefore, provided a hood for the body of the vulcanizer that loosely closes the top of the water compartment and forms a chamber above the gasolene compartment from which the spent products of combustion are dischargedfrom the side opposite or farthest from the tread of the tire. This hood is, preferably, vmade of sheet metal and is also of rectangular dimension.

It comprises four vertical walls, the upper ends of which are united by a substantially square top e of slightly greater area than the horizontal dimensions of the portion of the body of the vulcanizer devoted to the combustion compartment. The vertical wall f of this hood coming nearest the tread of the tire and disposed in the same general vertical plane as the partition C below it, is of substantially the same height as the side walls of the combustion chamber, and has its lower horizontal edge'g flanged toward thewvulcanizing-plate, and seated upon and loosely closing the top of the water compartment. The two vertical side-walls it, t, of the hood correspond, and extend downward below the flanged lower edge Vg of wall f, and lap down past the upper portion of the side-walls of the combustion chamber. The wall /c of this hood opposite wall f is a dropwall and extends down from the top thereof but a short distance and leaves a considerable opening between its lower edge and the top of the combustion chamber from which the products of combustion therefrom are discharged at such a. distance from the tire as to eliminate all possibility of injury to the same.. .Y

' The vulcanizer is secured to the rim of the wheel by means of lugs KK, projecting vlaterally from the side-walls of the combustion chamber thereof and chains J, J,fin substantially the manner shown in the aforesaid pending application for Letters Patent.

The hood is suitably secured to and mounted upon the body of the vulcanizer by screws j, j, or` otherwise, andwhere lugs K, K,interfere with the lower edges of the side-walls of` said hood they are recessed or cut, away. This hood, however, is prefer- Y n body, as the latter may, lsubjectto theconditions hereinbefore explained, be'rused withoutit, although I prefer its use.v i

After', the puncture in the tire or in the inner ,tube thereofhas been cleansedand treated 1n the usual manner, and one or more strips of cleansed rubber placed over the puncture, my improved vulcanizer is applied thereto in such manner that the vulcanizing-plate binds the rubber strip or strips in place and the water compartment will be in vertical position. The hood is then ltilted away from the tire, moving on the screws j, j, as pivot, suiiiciently to expose the top of the body ofthe vulcanizer. Water is then poured into the water compartment and then the gasolene poured into the combustion chamber in sufiicient quantity not to flow out of the slot. The hood is then tilted back in place and the gasolene ignited. The gasolene is permitted to burn itself out, and while doing this the apparatus is left to itself to heat the vulcanizing-plate and soften the rubber, which expands, when heated sufliciently, and is forced into and adheres to the walls of the puncture and to the tread of the tire, and, when properly done, effectually closes the puncture.

What I claim as new is:

l. A portable vulcanizer comprising a suitable body containing a water compartment next the outer vertical vulcanizingwall thereof, and a asolene compartment separated from said water compartment by a vertical partition, and a hood or cover tiltably mounted on said body above said gasolene compartment and provided with an opening in the side wall opposite said vulcanizing-wall.

2. A- portable vulcanizer comprising a suitable body containing a water compartment next the outer vertical vulcanizing'- wall thereof, and a `gasolene compartment separatedV from said water compartment by a vertical partition. and a hood or cover mounted on said body that closes said water compartment and above said gasolene compartment is provided with an opening in the side wall opposite said vulcanizing-wall.

3. A portable vulcanizer comprising a suitable body containing a water compartment next the outer vertical vulcanizingwall thereof, and a gasolene compartment separated from said water compartment by a vertical partition, and a detachable sheet metal hood mounted on said body above said gasolene compartment and provided with an opening in the side wall opposite said vulcaniZing-wall.

4. A portable vulcanizer comprising a suitable body containing a water compartment next the vertical wall thereof constituting the vulcanizing member, and a gasolene compartment separated from the water compartment by a vertical partition, and a detachable box-shaped sheet metal hood mounted upon said vulcanizer; said hood having the lower edge of one of the verticalwalls-thereof flanged toward said vulcanizingp, member and covering-said water compartment and having the vertical walls' thereof at right angles thereto extend to and supported by said vulcanizer, and the Wall thereof opposite said flanged Wall terminating at a short distance below the closed top of the hood.

5. A portable vulcanizer comprising a suitable body containing a Water compart ment next the vertical vulcaniZing-Wall thereof, and a gasolene compartment separated from said Water compartment by a Vertical partition Wall and provided with a slot in the outer wall thereof opposite saidvulcanizing Wall, in combination With a hood or cover mounted upon said body above said gasolene compartment and provided With an opening in its vertical side opposite said vulcanizing Wall from which alone the products of combustion are discharged. In Witness whereof I have hereunto set my hand this 16th day of September, 1913` VALLACE Gr. SANDFORD. Witnesses:
